Abstract: This disclosure relates to an assembly and method for attaching a heliostat to a foundation in a tower-based solar thermal CSP installation. A heliostat securing assembly for securing a heliostat to a tubular foundation post comprises an insert locatable within an upper opening in the foundation post, the insert defining an aperture for receiving a support shaft of the heliostat. A clamp arrangement, for locating the insert in the upper opening in the foundation post, has at least one inner or outer bearing surface configured to bear against at least one corresponding outer or inner bearing surface of the insert. One or more urging connectors, for connecting the insert and the clamp arrangement, is operable to urge at least one of the insert and the clamp arrangement toward the other in an axial direction of the foundation post.

Abstract: The present invention is directed to a cord fixture for attachment to a cord. The cord fixture includes a body having at least one side wall, and a slot in the at least one side wall for retaining the cord therein when the cord is in a fixed condition. The slot has a neck portion and an enlarged end portion adjacent the neck portion. The neck portion is configured to guide the cord into the enlarged end portion such that the cord can be releasably retained within the enlarged end portion.

Abstract: An excavator wear assembly comprising a mounting nose having a rear bearing face, a forward bearing face, an upper bearing face disposed at an angle between the rear bearing face and the forward bearing face, a front face substantially perpendicular to the forward bearing face and a rib extending over at least part of the upper bearing face, forward bearing face and front face; and a wear member having a rearwardly opening socket adapted to receive the mounting nose, the socket being at least partially defined by a top wall and a front wall, the wear member having a recess formed in the top wall and front wall adapted to receive at least part of the rib.

Abstract: A retaining pin assembly for an excavator tooth assembly. The retaining pin assembly has opposable locating members each having a shank portion able to be slidably insertable via a respective retaining pin aperture on opposite sides of a wear member into a transversely extending mounting aperture of a mounting nose of an excavator. Each locating member also has an enlarged inwardly convergent tapered wedge portion adjacent a normally outer end. The retaining pin assembly also has a tensionable retaining member extending between the locating members from one side of the retaining pin assembly. When tension is applied to the retaining member relative contraction of the locating members occurs to urge the wear member into engagement with the mounting nose by wedging engagement between each of the wedge portions and a rear wall of respective retaining pin apertures.
